Regarding the OP’s question (the following analysis is for reference only):
This issue with the steel strands can be remedied.
- Judging by the cut marks, the strands were severed using hydraulic tools. Specialized hydraulic shears or portable cutters are typically used for this purpose; however, a cut made by a standard cutter would usually leave a flat, clean cross-section.
- The two strands are different: one is a bonded strand, and the other (red) is an unbonded strand. (Please refer to this article for the differences between them; their application scenarios vary slightly, though it is possible for an unbonded strand to be stripped of its sheathing for use.)
- Steel strands generally require anchors to secure them. The exposed sections in the photo appear to be at the edge of the wall; if this is indeed the edge, excavating a bit further into the wall should reveal the anchors or steel plates securing the strands.
- If no anchors are visible, it implies the strands are under tension. Long-term structural stability must be considered; while there may be no immediate issues, the building could develop minor cracks over time due to crustal movements or environmental factors.
- It is recommended to first determine whether the two strands are under tension or to contact the contractor to see if they are aware of the situation.
Solution: An anchor connector can be used to join the two steel strands together.
